DUMP-CAR.

Application led December 22, 1913.

To all whom it may concern.'

Be it known that I, WINFIELD HANCOCK YosT, of the city of Montreal, Province of Quebec, Canada, have invented certain new and useful Improvements in Dump-Cars; and I do hereby declare that the following is a full, clear, and exact description of the same.

This invention relates particularly to cars having bottom dump doors hinged between the cross-bearers of the understructure and adapted to swing up and` downbetween the same. In cars of this type the doors on opposite sides of the cross-bearers are necessarily spaced from each other and from the sides of the latter to clear the same, thus permitting a proportion of the material being discharged to leak through the spaces between the doors and pile upon the rails and over the trucks of the car. As the doors, when open, extend out from the bottom edge of the cross-bearers the leakage spaces near the front edges of the doors will be increased in proportion to the thickness of the cross-bearers. The material is also liable to becomel jamlned between the side edges of the-doors and the cross-bearers and so obstruct the closing of the doors.

An object of the invention is to prevent leakage between the doors of dump cars and another object is to avoid the jamming of the material between the doors and crossbearers.

Another object is to combine with the leakage preventing means, a device for preventing the material whenk discharged at the side of the car from running back under the edge, of the doors and flooding the rails.

YFurther objects and advantages will be hereinafter described and particularly pointed out in the claims.

For full comprehension, however, of my invention reference must be had to the accompanying drawings forming a part of this specification, in which similar refer' ence characters indicate the. same parts and wherein: v

Figure 1 is a transverse section of a car embodying my invention, the doors at one side being open; Fig. 2 is a plan view, partly broken away, of a portion of the car; Fig. 3 is a side elevation of a car; with portions broken away; Fig. Il is a vertical sec- Speccaton of Letters Patent.

tion through one of the cross-bearers and taken on line 3--3 Fig. l; Figs. and 6 are transverse sections of one side of a car and illustrating modifications of my invention. j

The understructure of the car includes a center' sill 2 and cross-bearers 3 which lat ter may be of any approved construction and as shown in the drawings are formed with a web 't' stiffened by top and bottom flanges Sand 8a respectively. Doors 9 are hinged at 1 0 on opposite sides of the cross-bearers, the Hoor of the car being constituted by the top s ofthe center sill and crossbearers and the doors when closed as seen at the right hand side of Figs. l and 2. lVhen discharging the contents of the car, the doors are lowered to the position at the left of Fig. l, being operated by any preferred mechanism such as shafts l1 connected thereto by chains l2 adapted to be wound upon the shafts.

The cross-bearers necessitate the spacing of the doors one from the other and from the cross-bearers, to enable the doors when swinging up and down to clear the latter. Spaces are therefore presented between the side edges of the doors and when the latter are lowered to discharge the contents of the car, a proportion of the material leaks through these spaces, flooding the rails and piling upon the trucks instead of being deposited at the sides of the car and clear of the track. To avoid this leakage I provide aprons which are located just beneath the doors when the latter are open and extend across andvll in the spaces between the same. These aprons are disposed at substantially the same inclination as that of the doors when open and extend continuously from the hinged side of the latter to the free side thereof, being supported in any suitable manner but when applied to the usual form of cross-bearers, are preferably secured to the webs 7 thereof.

If the side edges of the doors are spaced so as to just clear the cross-bearers a difliculty is, encountered in that after discharging the contents of the car and when raising the doors to their closed position, it is found that particles of the material have lodged between the doors and cross-bearers and, upon movement of the former, become jammed and have to be removed before the doors can be raised. To prevent this I have spaced the doors a sufficient distance from the cross-bearers to present a substantial clearance and thus avoid the possibility of particles lodging in the spaces, the aprons being of the necessary width to span the latter.

The aprons each consists preferably of plates 14 secured to opposite sides of the web 7 by angle irons 15 and inclined downwardly from near the top of the crossbearer and the hinged side of the doors, out from the bottom edge of the crossbearer to a point substantially in line with the free edges of the doors when the latter are open and are of sufficient width to project laterally from the cross-bearer into the path of the doors. The bottom portions of the plates 14 are flanged as at 15a and secured to the cross-bearer by a web 17, a filler piece 18 being placed between the lower ends of the angle irons 15 and the latter riveted together. Then the cross-bearer is fianged the plate at the flanged side thereof is slotted as at 19 to fit over the flange and two con'iparatively short angle irons utilized.

As the aprons extend from a point near the hinged side of the doors down to a point substantially in line with the free edge of the latter it will be seen that the spaces between the doors are filled in for the full eX- tent of the sides of the doors and so form with the latter a complete chute from the door at one end of the car to the door at the other end. If only certain of the doors are lowered, the webs 17 fill in the sides thereof and prevent the material flowing sidewise from the same.

As the discharged material is liable to run back under the front edge of the doors and flood the rails, I have provided means for preventing this which preferably consist of a plate 20 at each side of the car and secured to the understructure just beneath the front edges of the doors when the latter are open. The plates extend substantially the full length of the car and reach sufliciently close to the ground to prevent the1 material running back and flooding the rai s.

It is desired to have the plates 20 removable and for this reason they have hooks 21 thereon which enter holes in the flanges 15a of the aprons 14, being readily applied to the car or removed from the latter after the material has been discharged. Before the doors are opened the plates are hooked in position so that when the material is discharged it will pile against the plates instead of flooding the rails, the plates resting against the trucks and being braced thereby. Formerly the discharged material flooded the rails and obstructed the movement of theV emptied car so that such material had to be removed from the track befo-re `the car could be moved, whereas with the present construction, the obstruction of the track is .avoided and the car enabled to be moved directly it is emptied.

In Fig. 5 I have illustrated my invention in connection with a door operating mechanism wherein the shafts 11a thereof move in inclined slots 12a of the webs 7 and when this mechanism is used the aprons are each divided into top and bottom sections 14a and 14b respectively to permit the movement of the shafts up and down in the slots 12a.

I have described the aprons as being rigid with the understructure of the car but it may be desired to have the lower portions movable, particularly those which are located above the car trucks and are therefore liable to be damaged by the jolting of the latter when the car is moving. For this reason the lower portions of the plates 14 may be hinged to the cross-bearers as at 22 and the webs 17 dispensed with (see Fig. 6), the free edges of the plates being connected to the free edges of adjacent doors by chains i3 or t-he like. lhen the doors are open the hinged portions of the aprons may rest upon the trucks of the car and when the doors are raised the plates 14 will, by means of the chains, be moved in unison with the doors and raised up above the trucks as shown in dotted lines Fig. 6, the chains 23 being of sufficient length to provide for the difference in the movements of the doors and plates.

That I claim is as follows:

1. In a car, dump doors and an apron supported independently of and adapted to extend between the doors when the latter are open.

2. In a car, dump doors and an apron supported independently of the doors extending between and located just beneath the latter when they are open.

3. In a car, the combination with a crossbearer, of a door at each side of the crossbearer and an apron secured to the crossbearer and adapted to extend between the doors when open.

4. In a car, the combination with a crossbearer and a door hinged at each side of the cross-bearer, of a downwardly inclined apron projecting' on opposite sides of the cross-bearer underneath the doors, a portion of such apron extending out from the bottom edge of the cross-bearer.

5. In a car, the combination with a crossbearer, of a door at each siderof the crossbearer and an apron secured to such crossadapted to extend between the sides of the latter.

7. In a car, swinging dump doors spaced from each other, a downwardly inclined hinged apron supported independently of the doors, located at the sides of and adapted to extend between the doors and means for raising the hinged apron.

8. In a car, swinging dump doors spaced from each other, a downward inclined hinged apron supported independently of the doors, located at the sides of and adapted to extend between the doors and means for raising the hinged apron in unison with the doors.

9. In a car, swinging dump doors spaced from each other, a downwardly inclined hinged apron supported independently of the doors and adapted to extend between the latter and a flexible connection between the doors and the apron.

l0. In a car, hinged dump doors spaced from each other, a downwardly inclined hinged apron supported independently of the doors and adapted to extend between the latter and a flexible connection between the free edges of the doors and the free edge of the hinged apron.

ll. In a car, the combination with a crossbearer, of an apron hinged to the crossbearer and inclining downwardly therefrom, hinged doors on opposite sides of the cross-bearer and adapted to overhang said apron and a flexible connection between the doors and the apron.

12. In a car, the combination with a crossbearer, of an outwardly extending liange upon each side of the cross-bearer and inclined downwardly from near the top of the latter, a plate hinged to and inclined downwardly and outwardly from the crossbearer, hinged doors on opposite sides of the cross-bearer, overhanging said iianges and a plate and a flexible connection between the doors and hinged plate.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
